What Does Red Light Therapy Do for the Body?

Although extensive research needs to be done, there are many known advances in using red light therapy to possibly improve one’s overall well-being. 

The interest behind the idea of using red light as a therapy came to life after NASA initially started experimenting on plant growth in space and later experimented with red light as a source that might help heal wounds in astronauts.

Since then, red light therapy has been widely medically accepted in photodynamic therapy and serves as an effective way that might help people with many different health conditions and issues.

Moreover, red light therapy (RLT) is a groundbreaking treatment using low-wavelength red light that may improve skin’s texture and appearance by reducing wrinkles, scars, acne, redness, and fine lines while at the same time possibly improving its elasticity and plumpness.

How does it work?

Even though some may think that the red light therapy process is super complicated, in reality, it is not. People start seeing the results when they start with the red light therapy, and it is consistent with sessions that last for a particular amount of time pre-established after a few sessions.

Red light can penetrate deep into the skin’s layers and tissues, even to the tissues or bones that are hard to reach otherwise. 

After the light comes in contact with the cells, it makes them produce more ATP, which, if you are not familiar with it, is a natural energy that your body produces, and it is used for the normal function of cells, tissues, and organs.

Moreover, this light is believed to increase the nitric oxide that later increases blood flow. When you have an increased blood flow in a certain tissue or organ, its quality increases. When we talk about the skin, it might start looking fresher, smoother, and rejuvenated.

So, this is how red light influences cells and might provide multiple benefits to our bodies.

For example, possibly improving the texture of the skin, reducing wrinkles and fine lines for smoother and younger-looking skin, reducing stretch marks, fading sun discoloration and age spots, reducing acne, healing wounds faster, psoriasis, eczema, rosacea skin condition, etc.

Moreover, red light therapy might have some promising results regarding androgenic alopecia, arthritis, chronic pains, and painful joints, and even possibly reducing the symptoms of dementia, depression, and helping kidney stones.

Might increase the production of ATP

Thanks to the power that the red light has, through numerous processes that occur after being introduced to one’s skin, it is believed to possibly help the cells increase ATP production. It is the key to healthy, vital, high-quality, and perfectly functioning cells across the entire body.

With the increased ATP, there are also increased levels of one chemical called nitric oxide, which might aid and promote blood flow. So, here the magic happens. Increased blood flow possibly means better quality of the tissues where the red light therapy was applied and a better looking and functioning of the particular bones, muscles, or skin cells.
